Fig. 2 .is a plan 'view of the battery shown in Fig. 1;' and l "Fign a fraginel Fig. 2 showingtwo-compartment.,container, in the "compartinents of ivlhichy the elements of a pair of, cells are "respectively disposel.r z i Referring'to the drawing and especially to Figs. lnnll reterenee characters 1, 1 representtlie ln'etallic containers ot' as pair ,of storage battery cells' comprising a battery. in each of which containers a `pllufality of Ialternatelyl arranged `positive and, Anegative elements or plates (not shown) are tlispos/ed,

The vent` tubes `are re- Hpeetively positioned b v 'bracing .inembers, one of which is shown at 18in Fig. 1. "Reference characters a. and represent the positive amlnegative poles respectively of one of the cells. which polesl extend through the top l of the cell. and are suitably ii'lsulatecl theren from', and which are respectively connected l eoiiueeted'iii series by `f means of a; plateQS `ofy l e istance which f onepolarity :in one ,t 'of opposite polarity y' interposed =resilient"v`va slie hold alle nuts 25 frein i'mtlnleafiingr and"neerl not be of insulating material.

extend through the plate and lrespectively into engagement with the tops or heads 4' of the containers, and preferably into screwthreaded engagement with depressed sockets 29 forming parts of the heads. The screws 27 each extends through a spacing sleeve 28 disposed between the plate 23 and the respective head 4, whereby the plate is maintained in proper position, and twisting or bending of the same, when the binding posts are screwed down on the plate. is prevented.

While the device has beendescribed particularly with relation to two independent cells, it is obvious that when the sides of the cells are brought into physical contact Without insulation therebetween, the two easings become in effect a single casing With a dividing partition, or a two-compartment container.

Assuming that the battery is being charged, and that the poles a, ZJ, c and d (Fig. 2) are alternately positive and negative in order as indicated, then the current 'Will travel from the positive terminal or pole a, through the electrolyte to the negative pole b, through the plate 23 to the positive pole c, and through the electrolyte in the second container or compartment to the negative terminal pole d. When so arranged, should the containers be in electric contact, the current after traversing through the electrolyte in the lirst compartment, will pass to the pole b disposed in its path rather than travel around this poleto the side of the container, which has the same polarity as the pole, for the electrolyte disposed between the pole and the adjacent side of the container offers a material resistance to the passage of the current. As the sides of the second container have the same potential as the pole c, there will be no tendency for the current to travel through the contacting There Will thus be eliminated any electrolytic decomposition of the containers which might result from a portion of the current traveling from the sides of the containers to the poles when the containers are in electric contact With each other. Should the battery, as a storage battery, be discharging then, the direction of flow of the current will be reversedA and current Will flow from the positive pole a of the battery, l

Thus, by connecting the metallic containers 1 electrically with a positive pole of one-cell and a negative pole of the other cell, these poles and the containers are maintained substantially at the same potential and the current, following the path of least resistance, passes through all the poles'in the usual order of cells connected in series rather than through the sides of the containers and the portions of the electrolyte adjacent thereto.

Referring to reference character G0 represents dividing the containerinto two compartments l', 1. Reference characters b and c represent the adjacent poles of unlike polarity of the battery elements which are respectively disposed in the compartments l', 1. The binding post 24 of each of the poles b and c is preferably directly grounded to the container top 4, and the elements 27, 28 and 29 employed in the construction shown in Figs. 1 and 2, are preferably dispensed with. The cells in the two compartments 1', 1 are connected in series by means of a plate 23 of low resistance which' is secured to the binding posts 24, 24 of the poles b and c by means of the nuts 25V.
